RADIATOR SHIELD.

This invention relates to improvements in metal cabinet construction, and particularly to means for connecting frame and panel elements to permit of assembling cabinets of various proportions from a minimum number of standardized stock parts.

The main objects of the invention are to provide improved forms of structural elements for building up metal cabinets of difto ferent sizes from stock parts and requiring no shaping other than cutting certain parts to length to suit the desired cabinet dimensions; to provide certain improved types of frame member sections adapted for ready is interconnection; and to provide improved means fordetachably securing said sections together.

A specific embodiment of this invention is illustrated in the accompanying drawings,

as in which:

Fig. 2 is an enlarged perspective view of the several frame member sections shown in detachably secured relation.

Fig. 9 is a sectional view taken on line 9-9 of Fig. 93.

Fig. 10 is a sectional view taken on line l010 of Fig. 2.

Fig. 11 is a sectional View taken on the line llll of Fig. 2 but includes a bolt omitted from Fig. 2.

In the form shown in the drawings, the built-up metal cabinet comprises angle corner members 1 whose longitudinal edges are flll nal edges are bent to form flanges disposed in a horizontal plane. Brackets 3 comprising angularly disposed arms 4t rigidly secured together as by the gusset 5, and secured to said arms 4t are wings 6 having offset portions 7 with longitudinally projecting lugs 8. The adjacent ends of the arms a are bent upon themselves in ti -shape for detachably engaging the shaped mar ginal flanges of the corner members. "the outer portions of each arm 4iand its wing 7 p are telescoped with the longitudinal folds of the rail member a and the longitudinal slots 9 in the flanges of the side rail members 2 receive the hook lugs 8 of the wings 5..

Intermediate frame members l0 have both their longitudinal edges bent upon themselves and rebent upon themselves to form marginal flanges of shaped cross section and are secured between the upper and lower side rail members through the connecting pieces 11 whose lower portions 12 telescope within the ends of the members 10 and whose upper portions 13 are offset and flanged at 1 4 to overhang the til-shaped marginal flangepf the rail members 2 as shown in Fig. l0.

Panels 15 are secured in place by seating their marginal portions in grooves formed by the fl-shaped flanges of the frame members and the assembled cabinet is held in rigid relation by the ornamental bolts or clamping members to, whose heads have overturned lips 17 which embrace the edges of the connector fittings 7 or ll, as the case may be and whose threaded stems 18 passing through the apertures l9 coact with nuts 20. Plates 21 are interposed between the nuts and the connecting pieces fl and serve as washers to afford a good bearing between the nuts and the adjacent frame members.

lit will thus be seen that the peculiar conformation of the assembled interlocking frame members and connectors reventh" the former from bein injured by lauclrling or distortion when t e ornamental clamping members tightly secure them together.

It will be noted that the several forms of frame members are each of uniform crosslllfl i v sectional form throughout and therefore maybe made and sold in long lengths and that cabinets of different sizes and for many purposes may be made up on the job by merely cutting the frame members and panels' to correct lengths. The frame members that require perforations, namely the rails 2, have a series of spaced perforations along their entire length so that they are ready for use when out in two at any medial point between adjacent perforations.
